`To all whom? it may concern:

Be it known that LJAMES P. POOL, a citizen of the United States,residing in the boroughof Brooklyn, in the county of Kings and city andState'of New York,l have invented certain new and usefuly Improvementsin Navigable Vessels, of which the following isa specification.

This lnventlon -relates lto navigable vesments in vessels of this class'whereby shall be rvessel. A Y In.. the drawings, Figure 1 is a sideeleva` tion of a sailing vessel constructed according to the invention.Fig. 2 is a plan view` of the mast 5 is operatively connectedwith theVload-carrying member I preferably by two operative connections 7 and8,- respectively -obtained greater stability in the movement Aofthevessel4 through the water, and consefquently greater speed'of movementand comort and security to persons carried by the same.

Referring with particularity to the'k drawings, l'designates theload-carryingmember of the improved vessel, and 2 thesail-carryingmember of the samepthe members 1 and -2 being [connectedtogether, as at 3, in such 'manner as to bevcapable of relative andpreferably pivotal movement. I The load-carrying member 1 is providedwith a counterwardly of the sail-carrying member 2, the

load-carrying member 1 extending in the '-main forwardly of thesail-carrying member 2. The load-carrying member 1 and the counterweight4 are rigidly connected together, so -that pivotal movement of thevmember 1 is accompanied by pivotal movement of the counterweight 4. Themember 1 and the member 2 are formed` and arranged to rest directly uponthe water, and thecounterweight 4'is adapted to depend -within thewater. y

The sail-carrying member 2 is provided with a mast 5,- which is mounted,as at 6, for oscillation i'na plane transverse to thevessel withinpredetermined limits,- but is incapable of oscillation in anyotherplane'. The

vtion a the former of which operates upon the loadcarrying member 1forwardly of the points 3 of pivotal connection of the load-carryingmember 1 with the sail-carrying member2, and the latter of whichoperative connections lis connected with the load-carrying member -1rearwardly of the said points`3 of pivotal connection with the members land 2.

As the mast 5 oscillates and careens under f lateral'air-pressure uponthe sail or sails, of

which latter a' single mainsail-Q is shown in the drawings, by meansofthe operative connections 7 and 8 the load-carrying member 1 l is deressed in the water and the counterweig t 4 is caused to rise both withrespect to the sail-carryin member 2, and-the careening tendency o theentire vvessel is transymuted into -a tendency toward further stability'of lthe entire vessel by the sinking or submer ing of the load-carryinmember 1 forward y of the points of pivota connection I 3. Thecounterweight 4 is of proper mass to eectually balance the portion ofthe loadcarrying member 1 forward of the points 3 of pivotal connection.Furthermore, the counterweight 4 as it depends in submerged posiing tobalance the same against lateral careening.

A preferred form of construction, arrangeds to the stability of thevessel', tendment, and operative connection ofV parts and members of avessel constructed according to the invention is as follows: Thesail-carrying member 2 consists of `a hull 10 of conventional or otherpreferred form tapering from its central portion to its bow .portion 11and its l stern portion 12. withv the customary deck 13, in which,approXimately at the central portion, is formed a laterally-elongatedmast-hole 14, through f which the mast 5 projects, such mast-hole beingprovided at its opposite end portions with opposed spring-buffers 15,against which the mast 5 bears in its oscillations lto and fro laterallyof the vessel, such buers 15 yieldingly opposing and terminating thesaid oscillations of the-masty 5. VThe mounting or stepping of the mast5, as at 6, so that the mast may be able to rock or oscillatelaterally,jis by means of a shaft 16, which extends longitudinally ofthe hull l0 beneath the deck 13 of the same and towhich .the lower endofthe mast 5 is directly connected in'upright position, 'as-at 17. Eachendlof the shaft 16 is provided with an elongated edged bearing 18 ,A

which rests within a bearing-opening 1.9 a

The 11u11 1011s provided i IOO IIO

separate standard 20, the standards 20 being spaced one from the otherand arranged in a line longitudinally of the hull 10. The bearings 18are free to rock in the bearing-openings 19 to a predetermined extent,equivalent to that permitted by the dimensions of the mast-hole 14.Suitable shoulders 19a on the shaft 16, in contact with and between thestandards 20, prevent longitudinal displacement of the bearings 1S inthe bearing-openings 19.

The load-carrying member 1 consists of a bowed hull 21a, which extendsaround and embraces the bow portion 11 of the hull 10 and is pointed atits forward or bow portion 21 similar to the corresponding portion ofthe conventional sailing vessel. rlhe rearward end portions 22 and 23taper rearwardly to the points of pivotal connection 3 with and atopposite sides of the hull 10 and approximately in the same transversesection of the hull 10 as that in which the mast 5 is stepped. Thecounterweight 4 is connected with the hull 21a by means of a bowed frame24, which extends around and embraces the stern portion 12 of the hull10 and is rigidly connected at its forward ends with the hull 21a at thepoints 3 of pivotal connection of the loadcarrying member 1 with thesail-carrying member 2. The counterweight 4 is of bulbous formation,tapering from its lowermost daring portion 25 to its uppermost portion26, which is directly connected with the frame 24. The counterweight 4serves as a counterbalance for the hull 21a; but as the latter restsdirectly upon and within the water the mass of the counterweight 4 isnot necessarily proportionate to the mass of the hull 21a, but is onlyof such weight as to steady the latter.

rl`he operative connection 7 between the mast 5 and the load-carryingmember 1 consists of a transverse bar 27 which is connected rigidly withthe mass 5 by an arm 28, which projects forwardly from the mast 5, andthe opposite end portions 28a and 29 of the bar 27 bear upon theopposite rear end portions 22 and 23 of the hull 21, just forward of thepoints 3 of pivotal connection of the members 1V and 2. The hull 10 maybe chambered or cut away, as at 30, at opposite sides of said hull 10 topermit the operative depression of the ends 28'rl and 29 for theirengagement with the hull 21aL in the careening or oscillation of themast 5.

The operative connection 3 consists of a stay 31 and a stay 32, whichstays are connected at their upper ends, as at 33, with the upperportion of the mast 5 and are respectively connected at their lowerends, as at 34 and 35, with the frame 24 at opposite points rearwardlyof the points 3 of pivotal connection of the members 1 and 2. The stays31 and 32 when the mast 5 is in perpendicular position may be normallytaut; but as the mast careens in either lateral direction the stay atthe side of the vessel from which it swings tends to elevate the frame24 at the corresponding side of the vessel, the other side beingslackened as, the frame 24 being rigid, the elevation of any portion ofthe same is accompanied by the elevation of the entirety. The traveler36 of the sheet 37 of the sail 9 is also connected at its ends with theframe 24 adjacent to the 'extreme rearward portion of the latter, sothat the pressure ofthe wind upon the sail and the careening of the mast5 tend also to elevate the traveler 36 and the frame 24 simultaneouswith the elevation of the frame 24 by the stays 31 and 32 and thedepression of the hull 21u by the transverse bar 27.

Between the hull 1() and the hull 21u at the sides and bottom portion ofsaid hulls an apron or flexible shield 38 may be extended, consisting ofoiled canvas or other suitable material, to prevent invasion ofthe spacebetween said hulls by water and objects, such as driftwood floating uponthe water, the passage of which obstructions between said hullsoperating against free relative movement of the hulls 10 and 21 andserving also to impede the progress of the vessel.

The vessel is steered by a rudder and tillcr 39 or other suitableequivalent means.

The operation and advantages of the improvements herein described willbe readily understood from the foregoing description, taken inconnection with the accompanying drawings, and the following statement.In sailing vessels of the conventional and ordinary type when the sameare proceeding in any other course than that dnectly before the wind thepressure of the air upon the sail or sails causes a tendency to lateralcurrent of the vessel, upsetting the stability of the vessel andmilitating against the comfort of persons aboard the same, as well ascausing capsizing under extreme conditions. In the navigation of avessel embodying the improvements described as the mast 5 within thelimits permitted by the construction of the supporting means 6 and theportions of the mast-opening 14 careens or oscillates laterally of thevessel and the air-pressure upon the sail 9 the operative connection 7between the mast 5 and the hull 21 causes depression of the hull 21awith respect to the hull 10, the obtaining of which result is assistedby the elevation of the frame 24 by the operative connection 8. Insteadof the enti-re vessel careening laterally the hull 21a is caused to sinkfurther in the supporting medium, securing increased stability of theentirety. The same effect is produced by the careening of the mast 5 ineither lateral direction through the instrumentality of the transversebars 27 and the stays 31 and` 32, and also the auxiliary liftingcapacity ofv the sheet 37 upon the traveler 36 and the frame IOO IIO

. 24. iThe frame; 24'together'with thefcoun-` terweight 4 and the hull21a are free to` swing pivotally at the points 3 Aof pivotal connectionof the load-carrying member 1 5 with the sail-carrying member 2,. .Thecounterweight 4 opposes the sudden andviolent. relative movement of thehulllO' and 'the' `hull 21a, and also lin its depending sub- .emergedposition thecounterweight acts as a ro Yweighted keel to oppose anyundue careening of the vessel. It'will be manifest that the degree ofsubmergence ofthe hull 21"* is proportionate to the degree of pressureof the propelling air u 'on the sail 9 and that at all r 5&- timesthevesse in its entirety instead` of befling careened overand-substantiallyrolled' A put .ofv the water, asis the `case in vessels of ordinarytype, 'is kept upon afsubstaneven keel within the water in a posil2otion, of satisfactory equilibrium.
